1.需要在以下方法中传入年月(-05)
2.代码如下，可供大家参考
getDate(val) {let date = new Date(val);let new_year = date.getFullYear(); // 取当前的年份let month = date.getMonth();let new_month = month + 1; // 取当前的月份let mon = "";let day = "";if (month > 12) {new_month -= 12; // 月份减new_year++; // 年份增}let firstDay = new Date(new_year, new_month, 1); // 取当年当月中的第一天let lastDay = new Date(firstDay.getTime() - 1000 * 60 * 60 * 24).getDate(); // 获取当月最后一天日期if (firstDay.getMonth() < 10) {mon = "0" + firstDay.getMonth();} else {mon = firstDay.getMonth();}if (lastDay < 10) {day = "0" + lastDay;} else {day = lastDay;}let startDate =firstDay.getFullYear() +"-" +mon +"-" +"0" +firstDay.getDate();let endDate = firstDay.getFullYear() + "-" + mon + "-" + day;this.dateRange = startDate + "~" + endDate;},
